ASTM B111 C68700 Aluminium Brass Tubes are made from a Copper-Zinc alloy that includes Aluminum and a small amount of Arsenic. This Arsenic serves as an essential inhibitor against dezincification, a form of corrosive attack. The typical chemical composition of this widely accepted industrial material is: Copper (76-79%), Aluminum (1.8-2.5%), and Zinc (Bal %), with trace amounts of Arsenic (0.02-0.06%), Iron (0.05% max), and Lead (0.05% max).
The outstanding characteristic of Inhibited Aluminum Brass is its high resistance to impingement attack, a critical factor for tube longevity. This alloy effectively resists the corrosive action of high-velocity salt and brackish water. In terms of mechanical strength, Aluminium Brass boasts a Tensile Strength of 414 MPa (60 KSI), a Yield Strength of 186MPa (27 KSI), and an Elongation of 55%. Furthermore, this Aluminium Brass Tubing is known for developing a protective, self-healing film around its surface, contributing significantly to its durability and ease of maintenance.
Tubes made from Aluminium Brass are highly recommended for use in applications where cooling water velocities are high, particularly in marine and land power stations where inhibited admiralty brass may fail from impingement. This makes Aluminium Brass Condenser Tubes ideal for use in Condensers and Heat Exchangers. Beyond power generation, this material is extensively used in various industries, including Evaporators, Desalination Plants, Ship Repair and Ship Building, Distillers, Refineries, Offshore Oil Rigs, and Radiators.
